PMA update failure
I don't have an answer to help you. That PMA update failure, seems to be a problem that many people have with Sony burners. Other brands of burners can also have that problem, but it seems to be a real problem for Sony burners.

RITEKG - 04 These are very good discs, but may not be very compatible with your burner. Some people have solved this problem by trying different media. It might work. Other's have solved this problem by getting rid of their Sony burner and getting one that doen't have that problem.
